Abstract:

 Mapo-Shanshenmiao Mn-Ag deposit situated in Lingqiu county, Shanxi province, is a poly metallic deposit with associated Pb and Zn. This deposit is located in west end of Yanliao fold zone, controlled by Yanshanian volcanics and faults. The ore bodies occur as stratified or lentoid or veinlike. The source of metals is derived from Gaoyuzhuang formation dolomite. The Mesozoic volcanic activities enriched them in the fracture zone around volcanic structure. It is a sedimentary  thermal modification type. Mn-Ag deposits are rare in China. It is of prospective market, large resource and convenient mine development condition, indicating a good development prospect.

Key words:  Mn-Ag deposit, geology, resource development, Shanxi province

摘要：

山西省灵丘县马坡—山神庙锰银矿床是一个以锰银为主，伴生有铅锌的多金属矿床。矿床地处燕辽台褶带西端，受燕山期火山活动和断裂构造控制明显，矿体赋存呈似层状、透镜状或脉状产出。矿体富集规律显示，矿体中的锰银铅锌等矿源来自长城系高于庄组的白云岩地层，经中生代火山活动使矿质富集于火山构造周围的断裂带中，属于沉积—热液改造型锰银矿床。锰银矿是我国的稀缺矿种，用途广泛。通过对马坡—山神庙锰银矿床的市场分析、资源分析和建矿条件分析，均表明马坡—山神庙锰银矿具有广阔的市场前景、良好的资源保障和有利的建矿条件，其资源开发前景良好。
